Questions
How big is the ADS1235EVM PCB?
It measures 50 × 25 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ADS1235EVM use?
73 parts, built around the ADS1235QWRHMRQ1, UCC27524DGN and LM27762DSS. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ADS1235EVM KiCad files?
From the Iam-JB/LAAS-ForceFrontEnd repository on GitHub, at the commit this page was made from: the board is ADS1235EVM.kicad_pcb and its schematic ADS1235EVM.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ADS1235EVM design in my own project?
Its repository states no licence, so its author keeps all rights: ask Iam-JB before reusing the design.
